Beginners Mind again, for this: The Hubble Extreme Deep Field

2012 -

One of the first cosmological images which really and truly blew my mind as a young adult was the Hubble Ultra-Deep Field. Basically the idea was “Hey, what happens if we take our most powerful telescope and point it somewhere that’s pretty much empty and just stare at that spot for a really long time. What would we see?” The answer to that question was “We see somewhere in the neighborhood of 10,000 very distant galaxies.” Pause and let that marinate for a moment.

Here is a closeup on one small area of the image, a random part that I thought looked cool:

For a long time I left that as the wallpaper for my computer at work and I’d come in every morning and stare at the image while my slow computer took forever to finish loading windows. What was cool about having it as the wallpaper I had to look at while I waited for the machine to become usable was just how much there is to look at in there. As long as I stared at it, I’m certain there’s oodles of things I still didn’t notice. Looking at it first thing in the morning too, when the mind is raw and still gradually awakening surely added some awe to the effect as well. It’s staring into an abyss. Staring into infinity. And knowing that it stares back at you too…

As a humorous aside, I’ll note that the “Hubble Ultra-Deep Field” is actually the sucessor to the “Hubble Deep Field” which showed a different region in space. And this new image, the “Hubble Extreme-Deep Field” is a closeup of a smaller section within the Ultra-Deep Field image, adding around 5,500 galaxies to the original 10,000+. When the James Webb Space Telescope goes online, they have plans to image the same area with it’s mighty Infrared sensing capability. What will that image be called? The Ultra-Extreme Uber-Deep Field Tournament Edition Plus. Director’s cut. Enhanced, expanded edition. Two. Strikes Back. Reloaded. Chopped and Screwed. Remix. Turbo.

Whatever, it doesn’t matter what it’s called. Just, everyone, do me a favor: full rez this new baby and spend at least two minutes staring, thinking about what it shows:

Everything on the internet, everything in a book, everything you’ve ever heard, learned, imagined, or even dreamed, in the most remote recess of your subconscious, is all within the realm of the ‘Earth’ experience. And Earth is a single, small terrestrial planet out in some sleepy backwater arm of the Milky Way, a perfectly average spiral galaxy with about 300 billion stars, and about as many planets, with maybe 10 billion of these being in the goldilocks “habitable” zone. Or at least habitable to “life as we know it”. Nevermind moons, nevermind thermally-supported life, nevermind ‘Steppenwolf’ planets that were flung from their parent stars. If the entire breadth of human knowledge, emotion, and experience resides within our differential-unit-small grain of sand that’s floating in the Milky Way swimming pool, then try to concieve of the vast diversity of lifeforms, cultures, natural wonders, and sub-realities residing within the oceanic field of view of this image, depicting thousands upon thousands of distant galaxies. Try to imagine traveling there, surveying them. Imagine exploring just a handful of those galaxies and chronicling the habits of their residents.

How could we explore it? First we’d need to aggressively master interplanetary voyages, remote communication and colonization. Fly probes and listening devices to the Kuiper Belt. Mount them to passing comets for a long voyage back out to the Oort cloud. Use those to learn about the radiation and galactic wind in interstellar space. Develop shielding, life prolonging and hybernation capabilities for deep space travel. Contact alien cultures within our own galaxy and master inter-species diplomacy. Develop non-invasive, non-destructive ways to study primitive life still early in its evolutionary tree. Catch the best bacteria to help us live longer, retain more knowledge. Authoritively chronicle the Milky Way with billion-year data storage capability. Pool resources with other intelligences to build intergalactic ships or probes. Scatter them in all directions to search for points of interest. Then, finally, research ways to reach the most distant of galactic neighborhoods like the ones we see in these pictures. My point: The actual exploration of these places is not something that’s a few ‘ages’ away in terms of a civilization. Exploring these places is an act for intelligences unthinkably more sophisticated than our own… But we can dream of it.

When I look at this, I like to focus in on individual places and try to imagine what might be there. I like to find a pretty looking galaxy and think about what planets might be inside of it. Or sometimes find a teeny sub-pixel dot and wonder if that less-than-a-pixel point is a whole giant supergalaxy, burgeoning with life forms, interstellar commerce & conflict, culture & craftsmanship. Maybe these two galaxies colliding are locked in an interspecies war millions of years long. Maybe they’ve evolved organic-electronic synthetic intelligences that can instantly teleport between host bodies, allowing them to be anywhere their race has ever traveled instantaneously. I wonder what their music sounds like. I wonder what senses they have. Can they “see” radio waves? Does their culture have money, or government? I wonder what “pleasure” or “sex” means to them? Or consciousness? I wonder what THEIR telescopes have discovered about the formation of the cosmos. Does it look “the same in all directions” from the far-far edge of what we humans can see?

It’s fun to try envisioning all these things. And then humorous, in a zen sort of way, genuinely humorous, knowing that it’s impossible. You can’t. You’re looking at something so much bigger, ancient, and wilder than the capability of the feeble human brain to comprehend. The are not human words in any language to meaningfully describe what any of these Hubble Fields show. These images, obscured by the thick, nearly-opaque veil of distance, give the most fuzzy, teasing glimpse of something beyond us. Something beyond even what our most distant descendant will ever become. I find that deeply exciting. This picture shows, unquestionably, indisputably, that the universe has more to explore than is possible to explore. What better reason to be alive in this cosmos?
